Do you think a Japanese localized AppleWatch or a Japanese localized iPhone with a Japanse credit card work in this context? (I will use iPhone 7 plus or Apple Watch 3) I always have doubt to use ApplePay while I'm traveling outside Japan.
It entirely depends on your bank. My US banks' cards work fine in the UK via Android Pay.
Thus I will bring my oyster card anyway...
That's certainly safer. Regards, John Levine, johnl@xxxxxxxx, Primary Perpetrator of "The Internet for Dummies", Please consider the environment before reading this e-mail. https://jl.ly
